System Description [10/2017 - 10/2020]

The electronic shift lever system electrically controls the transmission parking lock mechanism and shift control mechanism.

The shift control ECU judges the vehicle condition based on the information from each sensor, switch and ECU and performs appropriate shift control based on the driver's operation of the shift lever or P position switch.

If a malfunction occurs in the electronic shift lever system, the master warning light illuminates in the combination meter assembly (according to the malfunction mode, the shift position indicator (P, R, N, D, M) turns off (not in all cases)) and a warning message is also displayed on the multi-information display.

When the shift control ECU detects a malfunction, the DTC is stored in the hybrid vehicle control ECU.

1. Shift position indicator (P, R, N, D, M) ON (indicator illuminated (normal)) or OFF (indicator off (not normal)) is displayed.

1. A reject function is equipped to reject incorrect shift switching when the shift lever is operated incorrectly.
2. When the reject function operates, the current shift state is maintained or switches to the neutral (N). The buzzer in the combination meter assembly sounds (2 times consecutively or once) and the master warning light blinks. Also, the recommended handling method is displayed on the multi-information display.
   REJECT FUNCTION OPERATION CHART
   
   

   Shift operation performed by reject function	Shift state after reject function operation	Message displayed on multi-information display
   Changes the shift state when auxiliary battery voltage was low	Maintains current shift state	Battery low Shifting unavailable See owner's Service Information
   Changes the shift state to and from park (P) within a short period of time	Park (P)	Shifting unavailable Wait a moment and Shift again
   Changes the shift state from park (P) or neutral (N) to manual (M)	Maintains current shift state	Vehicle must be in D to shift into M
   Changes the shift state to drive (D), reverse (R) or manual (M) when the power switch is on (IG) and the READY indicator is off Changes the shift state from park (P) when the READY indicator is blinking or the engine is cranking Changes the shift state from park (P) when the required voltage to change the shift state is not available	Park (P)	Hybrid system must be READY to shift
   Changes the shift state from park (P) with brake pedal not depressed	Park (P)	Depress brake to shift
   Changes the shift state directly to manual (M) from reverse (R)	Neutral (N)	Shifted into N Vehicle must be in D to shift into M
   Changes the shift state to drive (D) while backing up	Neutral (N)	Shifted into N Vehicle must be stopped to shift into D
   Changes the shift state to reverse (R) while driving forward	Neutral (N)	Shifted into N Vehicle must be stopped to shift into R
   Changes the shift state to park (P) when driving	Maintains current shift state	-
   Changes the shift state form park (P) when accelerator and brake pedals depressed simultaneously	Park (P)	Release accelerator to shift
   Changes the shift state to neutral (N) when the system detects the shift lever was moved to N but not enough time elapsed for manual switching	Maintains current shift state*	Temporarily hold shift lever in N position to shift into N

   *: The shift state may shift to neutral (N) depending on the driving conditions.
